Re: Difference between BiPAP and ASV

I'm not even sure another sleep study would be of that much help - do you have to go to the same clinic?. Is the backup machine the same model? Seems like on this board I've heard some not so good stuff about the NHS...Chalkie wrote: ↑Thu Apr 05, 2018 4:20 amAll sounds eminently sensible. However, with the NHS they don't want you messing around with the settings.raisedfist wrote: ↑Tue Apr 03, 2018 12:03 pmI think you're better off starting from scratch and using the forums help to get you some better settings. Either the technician doesn't know what they are doing, or they are just not interested in helping you. Or both.Chalkie wrote:
So should the pressures have been raised? Feeling lost here.
The technician just whacked the pressure up, with no discussion, and sent me packing with a new mask and a ticking off for admitting to using the forums.
Since you have the BiPAP S/T, I would switch it to Spontaneous "S" therapy mode, and set your pressures at something like IPAP 8 and EPAP 6 and see what happens. You should get less mask leaks, and with the lower pressures, especially less pressure support, there is less chance of the pressures themselves causing centrals. If you still have a ton of centrals, we can trial switching back to S/T mode with a low backup rate, and see if that helps. If that doesn't help the centrals, then probably off to ASV land you will need to go.
What I COULD do is use the backup machine they have given me (and probably forgotten I have) and learn how to tweak the setting on that.
I reckon another sleep study is called for tbh. I agree I need to start from scratch.
